stringregexp match

[gcue]

hello world

i am currently using this

$aDate = StringRegExp($date, "(?i)(\V+)(\d{8})\V(\d{4})", 3)

to successfullly match these

$string = "IMG00136-20100524-0109"
$string = "IMG00136_20100524_0109"
$string = "IMG_20000526_100019_402"
$string = "IMG-20120615-00028"
$string = "IMG_20120615_00028"
$string = "Texas-20111117-00060"
$string = "Texas_20111117_00060"
$string = "Southwest San Marcos Valley-20111110-00046"
$string = "Southwest San Marcos Valley_20111110_00046"
$string = "Long Island-Laketown-20110526-00023"
$string = "Long Island-Laketown_20110526_00023"

however these do not match unless i add an \A at the beginning (but if i do that then the ones above do not match)

$string = "20141119_193702"
$string = "20141119-193702" 

any way to match both?

thanks in advance !

Try (\V*) instead of (\V+)

You might want something like this

#Include <Array.au3>

$string = ""
$string &= "IMG00136-20100524-0109" & @crlf
$string &= "IMG00136_20100524_0109" & @crlf
$string &= "IMG_20000526_100019_402" & @crlf
$string &= "IMG-20120615-00028" & @crlf
$string &= "IMG_20120615_00028" & @crlf
$string &= "Texas-20111117-00060" & @crlf
$string &= "Texas_20111117_00060" & @crlf
$string &= "Southwest San Marcos Valley-20111110-00046" & @crlf
$string &= "Southwest San Marcos Valley_20111110_00046" & @crlf
$string &= "Long Island-Laketown-20110526-00023" & @crlf
$string &= "Long Island-Laketown_20110526_00023" & @crlf
$string &= "20141119_193702" & @crlf
$string &= "20141119-193702" 

$aDate = StringRegExp($string, "(?i)(\V*)(\d{8})\V(\d{4})", 4)  ; $STR_REGEXPARRAYGLOBALFULLMATCH 
Local $res[UBound($aDate)][3]
For $i = 0 to UBound($aDate)-1
   $res[$i][0] = ($aDate[$i])[1]
   $res[$i][1] = ($aDate[$i])[2]
   $res[$i][2] = ($aDate[$i])[3]
Next
 _ArrayDisplay($res)

very helpful

thanks again for all your help!

Very nice mikell. I like the use of $STR_REGEXPARRAYGLOBALFULLMATCH. I didn't know it was possible to call directly a subarray item with ($aDate[$i])[1].

 

[iamtheky]

best example for magic number 4 I have seen, that needs its own thread.  Even moreso with the direct access of an array in an array.

Seriously Mikell, i think you have most certainly added back into routine consideration, a storage option I had disregarded for the most part as being cumbersome compared to alternatives.  

I would call this shorthand, but is there a proper name for that type of syntax, that would be a fitting title for a thread consisting of examples?

About alternatives you probably mean this commonly used one

$aDate = StringRegExp($string, "(?i)(\V*)(\d{8})\V(\d{4})", 3)  ; $STR_REGEXPARRAYGLOBALMATCH
Local $res[UBound($aDate)/3][3]
For $i = 0 to UBound($res)-1
   $res[$i][0] = $aDate[$i*3]
   $res[$i][1] = $aDate[$i*3+1]
   $res[$i][2] = $aDate[$i*3+2]
Next
 _ArrayDisplay($res)

But I personally prefer the flag 4 regex
Referring to the last example in the helpfile this flag 4 way could be written like this

$aDate = StringRegExp($string, "(?i)(\V*)(\d{8})\V(\d{4})", 4)  ; $STR_REGEXPARRAYGLOBALFULLMATCH 
Local $res[UBound($aDate)][3]
For $i = 0 to UBound($aDate)-1
   $aMatch = $aDate[$i]
   $res[$i][0] = $aMatch[1]
   $res[$i][1] = $aMatch[2]
   $res[$i][2] = $aMatch[3]
Next
 _ArrayDisplay($res)

Concerning the ($aDate[$i])[1] syntax I don't know where it's mentioned in the helpfile
I saw it once in a topic and found it very useful and handy so I kept this tip stored into a couple of little grey cells for further use
